## ማብራሪያ

Speedix profiles PHP execution on your WordPress site, showing exactly which hooks
and plugins are slow. Unlike page speed tests that just show load time, Speedix 
shows you _why_ your site is slow.

Built for developers, agencies, and site administrators who need to diagnose performance
issues at the code level.

#### What It Does

Measures every WordPress hook with microsecond precision and traces slow callbacks
back to their source plugins using PHP Reflection. You get a clear breakdown of 
where time is spent: Core vs Theme vs Plugins.

The dashboard shows a health score (0-100), highlights the slowest hooks, and tracks
performance trends over time. WooCommerce sites get a dedicated tab with categories
for Checkout, Cart, Products, Orders, and more.

#### Safe for Production

 * Sample rate control (10-100% of requests)
 * Threshold filtering to only log slow hooks
 * Overload protection auto-pauses if overhead spikes
 * Auto-cleanup from 1 hour to 7 days retention

Quick presets let you switch between Safe Mode (10% sampling), Balanced, or Detailed
profiling with one click.

#### WooCommerce Support

Works with HPOS (Custom Order Tables) and Cart/Checkout Blocks. Tracks checkout 
complexity: payment gateways, shipping methods, coupons, and session size.

#### Export Options

CSV, JSON, and Markdown exports for reporting and analysis.

#### Why Not a Page Speed Test?

GTmetrix and PageSpeed measure frontend delivery. Speedix measures server-side PHP
execution. They answer different questions. Use both.

#### Privacy

All data stays in your WordPress database. No external API calls, no tracking, no
telemetry. GDPR compliant by design.

#### 100% Free

Every feature is included. No pro version, no upsells.

## መጫን

 1. Upload the plugin files to `/wp-content/plugins/speedix/`
 2. Activate the plugin through the ‘Plugins’ menu in WordPress
 3. Go to Tools > Speedix
 4. Complete the Quick Setup wizard (recommended) or configure manually
 5. Enable profiling and visit your site to start collecting data

## የተለመዱ ጥያቄዎች

### Will this slow down my site?

Minimal impact when configured properly. Use “Safe Mode” preset (10% sampling, 2ms
threshold) for production sites. The plugin includes overload protection that automatically
pauses profiling if overhead exceeds safe limits.

### Will this break my site?

No. Speedix uses read-only profiling with built-in safety limits. If overhead gets
too high, it automatically pauses for 1 hour. You can also disable at any time from
Settings.

### How is this different from debugging plugins?

Debugging plugins show detailed info about the current request. Speedix takes a 
different approach – it aggregates performance data over time to identify persistent
slow spots and trends across many page loads.

### Why am I seeing 0 hooks collected?

Check these in order:

 1. Is profiling enabled? Toggle must be ON in Settings.
 2. Is the page whitelisted? Only pages in “Pages to Profile” are tracked.
 3. Sample rate too low? At 25%, only 1 in 4 requests profile. Set to 100% for testing.
 4. Threshold too high? Set to 0ms temporarily to capture all hooks.
 5. Are you visiting the right page? Make sure it’s in your whitelist.

### Why is the plugin breakdown empty?

Enable “Identify plugin sources” in Settings. Without this, hooks are captured but
not attributed to specific plugins.

### What does “unknown” plugin mean?

Appears when callbacks can’t be traced to source files. Common causes: anonymous
closures, dynamically generated functions, or code outside plugin/theme directories.

### Can I leave it running on production?

Yes, especially in Safe Mode. Sample rate ensures only 10-25% of requests are profiled,
and overload protection prevents performance impact.

### How long is data kept?

Default: 24 hours. Configurable from 1 hour to 7 days. Data is automatically cleaned
up via WordPress cron.

### Does it work with page caching?

The profiler measures uncached PHP execution. Cached pages bypass PHP entirely and
won’t appear in profiles – this is expected behavior since cached pages are already
optimized.

### Can I use this on multisite?

Yes. Each site maintains its own profiling data. Network admins can access the dashboard
on any site.
